In U. S. immigration context, the term “legalization” is colloquially used to refer to a process whereby a person illegally present in the country can obtain lawful permanent residence. Since 1929, the US law has provided the legalization procedure known as registry, which simply requires the applicant to prove that he has continuously resided in the country since before a certain specified “registry date” (originally, 1921; presently, 1972), and is not inadmissible on other grounds (criminal history, etc.).[1][2] One legalization proposal that was widely discussed recently[when?] was the DREAM Act.
